I've used it in the past. I didn't find it to be especially useful myself. Mostly what I wanted was the smart completion for PHP. I've played with if for C++ and it was pretty nice, but given that I never write C++ not useful for me personally. I've been told all it would take is writing some sort of simple parser for the completion to work, and it's been bought up on the CEDET mailing list several times but never gone anywhere. (Admittedly, I could probably write one myself if I wasn't so lazy so I'm as much to blame for it not going anywhere as anyone else.) I can't really speak to the UML stuff as I've never used it, but it looks pretty neat if you're into that kinna thing.
